Dear Rxperts, Through Windows OS, I created shortcuts (paste as shortcut) to excel spreadsheets ( with "xlsx" as the file extension).

Hi! I'm manipulating XLSX data using RODBC, however a limitation which appears to be driver based is that you can't clear or drop sheets from the XLSX files, as per the following example: > library(RODBC) > xlsx<-odbcDriverConnect("DRIVER=Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb);DBQ=c:\\documents and settings\\desktop\\testxlsx.xlsx; ReadOnly=False") >

Hola. En un cierto directorio tengo archivos excel y de otros tipos. Cada uno de ellos corresponde a una encuesta a una empresa X.

Hi, I have a bit of a problem with as.numeric or as.double. I read in an excel-file (either xlsx::read.xlsx2 or gdata::read.xls). Select a subset and then try to make it numeric: # read in the excel-file alldata<-read.xlsx2("input.xls",1) # select the subset s<-subset(alldata, select=c("cI","cII","cIII","cIV","cV")) # unluckily

Hola, Pensé que esto iba a ser trivial en R, pero me estoy encontrado muchos con mi problema en internet, y que las soluciones ofrecidas no terminan de funcionar.

Hola, @javier, me gustaría no tener que hacer nada de forma manual, ni por fuera de r, rstudio. Es decir, el típico comando de linux que me convierta de xls a csv prefiero no usarlo. Me gustaría hacerlo todo desde R. @jorge -> Con RODBC me salta -> Error: could not find function "odbcConnectExcel" Lo que creo que es inevitable en Ubuntu

Dear R Discussion List, I would like to save my data as a xlsx file. But at first I need to split it and then save each series into a Excel column. Please take a look at the following code: dados <- data.frame(matrix(c("2012-01-01","2012-02-01", "2012-03-01","2012-04-01","2012-05-01","2012-06-01",

I'd like to be able to read multiple sheets from an excel workbook and use the sheet name to name the resulting dataframe using RODBC. at the moment i've figured out how to do it the long way (see below) but feel sure that there is a speedier & possibly automatic way to do it in R. i've tried to run a loop using sqlTables but it seemed to break the connection. unless i've

Gracias Jorge por contestar tan rápido. Con gdata hago eso del path, y directamente con el fichero, lo vi en una web, y he intentado todas las opcioens que he visto.

Hi, i'm trying to read some data from excel files but it seems that neither xlsReadWrite nor sqlFetch (RODBC) doesn't like the format (Excel 5.0). When i open the file in Excel and save it in a new format Excel 97 -2003 everything works fine.
